Problems solved by technology

[0004] Generally, time complexity is used to evaluate the computational workload required for the execution of an algorithm or a program. Time complexity can quantitatively measure the time spent by different algorithms, thereby providing a basis for system designers to judge the pros and cons of algorithms or programs. It is impossible to calculate the specific time taken by an algorithm or program to execute

Abstract

The invention relates to a timestamp based method for measuring million instructions per second (MIPS) required by an embedded software module. The invention relates to a method for measuring MCU time taken or consumed by execution of an embedded software functional module in medical electronic equipment, and particularly relates to observation of MIPS of the MCU required by execution of a digital filter module in medical electronic products. The method is implemented as firmware in an embedded real-time operation system. The measurement method can be repeatedly used in advanced research and development activities of other medical electronic products carried out by use of the real-time operation system.

Description

technical field [0001] The present invention relates to a method for measuring the MCU time occupied or spent when an embedded software function module is executed in a medical electronic device, in particular to a method for observing the MIPS number of an MCU required for the execution of a digital filter module in a medical electronic product, and The method is solidified in the embedded real-time operating system, so that this measurement method can be used repeatedly in the development of different medical electronic products. Background technique [0002] The medical electronic equipment industry is in the ascendant, and the vast majority of medical electronic equipment is an embedded system, the core of which is one or more MCUs, and the MCU stores program codes pre-programmed according to specific purposes. Many resources such as / D, timer, DMA, UART, and external circuits connected through the I / O interface have a computer system that can complete specific functions...
